Identifying the potential compute performance of a heterogeneous architecture is a daunting task with the currently available benchmarks, as they focus either on monolithic application use cases or on isolated compute operations. Real-world scenarios on these architectures require an optimal utilization of the available compute resources, such as the CPU, GPU, and hardware accelerators.
"Optimal use of heterogeneous architectures implies load balancing of the compute tasks and distribution of data across multiple compute resources and separate fine-tuning for their individual performance profiles. This requires intimate knowledge of the architecture of the individual compute elements and of the heterogeneous architecture as a whole," said Rafal Malewski, chair of EEMBC's Compute working group and senior graphics engineering manager at NXP Semiconductor. "EEMBC has set out to create a benchmark that assists in identifying the performance criteria of the heterogeneous compute architecture and in determining the true potential of the architectures for real-world application use cases."
"As one of the pioneers of the graphics industry, it's been very interesting to see GPUs evolve into a main component of heterogeneous compute architectures, often referred to as GPU-Compute. This evolution is being driven by highly-parallel, computer vision, deep-learning, and neural-net applications in market segments such as automotive, mobile, scientific, and industrial," said Dr. Jon Peddie, president of Jon Peddie Research. "The competition will be fierce amongst the many software and silicon providers targeting the heterogeneous computing industry, and there will be a great need to help sort this out with real-world benchmarks, such as the one being developed by EEMBC."
"All EEMBC's benchmarks are about being repeatable, verifiable, and certifiable, and this compute benchmark will be no different," said Markus Levy, EEMBC president. "To ensure consistency between compute implementations, EEMBC's compute benchmark's framework will utilize the popular Khronos OpenCL 1.2 Embedded Profile API, which is supported by most vendors providing a heterogeneous architecture. Once the OpenCL reference implementation is validated, the benchmark will be open for vendors to submit platform specific optimizations."
